The last user of MAY_HAVE_SPARSE_IRQ is sh/csky, but the sh use SPARSE_IRQ, MAY_HAVE_SPARSE_IRQ could be kill. and for csky, it uses statical allocation by default. So MAY_HAVE_SPARSE_IRQ seems to be useless, no need to maintain a separate MAY_HAVE_SPARSE_IRQ config, kill it. Also cleanup the kernel/irq/Kconfig a little. v2: - drop all the NR_IRQS suggested by Geert - don' use SPARSE_IRQ for csky by default, suggested by Guo.
